| // FEAT_CHK is mandatory from v8.0-a, but a clang user may not be using the LLVM |

| // print `chkfeat x16`. |

| // So, in this case, we only print `chkfeat x16` from v8.9-a onwards, as an |
| // assembler that understands v8.9-a will understand `chkfeat x16`, and those |
| // that understand previous versions may not. |
